More than 1,500 scientists on Thursday released a letter declaring that they are “appalled by the recent retaliation against colleagues who dared to exercise their civil and human rights” with a peaceful protest at a December conference in Chicago.

Published by news outlets around the world in English, French, and Portuguese, the letter comes after Rose Abramoff and Peter Kalmus unfurled a banner that read “Out of the lab & into the streets” just before an art and science plenary talk at the Fall Meeting of the American Geophysical Union (AGU).

“As scientists, we make detailed observations and carefully design experiments and models to understand the causes, processes, and implications of climate change” the letter states. “We stick to facts and do our best to inform policymakers and fellow citizens, and train students in rigorous scientific methods.”

“Importantly, climate scientists are citizens and humans too,” the letter adds. “As citizens, we have our own views of the world and we engage in the public debate in the ways we see fit. As humans, we have the inalienable right to express our opinions in a peaceful manner.”

Citing scientific conclusions about the causes of the climate emergency and the urgent need to address them, the letter stresses that “more than ever, we need to engage actively as citizens-who-are-scientists in working for the mitigation of greenhouse gas emissions and the swift transition to a low-carbon future.”

The AGU—which has over 60,000 members and 23 peer-reviewed journals— describes the annual conference as “the most influential event in the world dedicated to the advancement of Earth and space sciences.” The organization launched a probe into the protest.

While Kalmus still works at NASA’s Jet Propulsion Laboratory, the Oak Ridge National Laboratory, which is sponsored by the U.S. Department of Energy, fired Abramoff over the demonstration, which she wrote about in a New York Times opinion piece earlier this month.

Abramoff and Kalmus—who have both been arrested for previous climate-related civil disobedience—disrupted the AGU event for less than 30 seconds. Someone swiftly ripped the banner from the scientists’ hands and AGU staff escorted them from the stage. Kalmus tweeted that “the AGU took our badges and kicked us out of the meeting.”

HEATED reported Friday that the day before the protest, during a grief circle at the conference that was asked to disperse to clear a hallway, “Abramoff said she gave her phone number to one of the AGU officials. HEATED independently identified this official as the senior vice president of meetings, Lauren Parr.”

The report added that “after being expelled from the conference, Abramoff said she received a phone call from Parr (Abramoff did not name Parr in the conversation with HEATED), in which Parr threatened arrest if the two returned; said their research would be removed from the conference; and that AGU would contact their work institutions.”

Parr declined to comment while an AGU spokesperson declined to confirm those details and “also attempted to prevent HEATED from naming Parr, claiming she had been receiving significant harassment and death threats,” according to the outlet.

The new letter—signed by members of the Earth system science community from dozens of countries, including several authors of Intergovernmental Panel on Climate Change reports—charges that “the response with which they were met was by far disproportionate,” calling out both “the AGU’s actions against them and the recent retaliation that followed.”

The letter continues:

We argue that the cost of silence in the face of such unfair and disproportionate treatment, for the scientific community and the planet, would be too high. The heavy-handed and unjust responses to a short banner unfurling not only threatens the careers of two scientists, it also discourages researchers—and especially early-career scientists—from engaging with their colleagues and society and to speak out about the urgent need for climate action. We are deeply concerned by a decision that tells scientists that they risk their careers if they dare speak out or engage in advocacy that is not formally approved. Employers should not punish scientific researchers for participating in nonviolent climate action. Academia and membership organizations like AGU should be safe spaces for freedom of expression.

We stand by our fellow climate scientists who express frustration with the lack of meaningful climate action within the scientific community and the public, who bring attention to the urgency of the moment in a nonviolent manner. We stand by Rose and Peter.

Scientists and others from across the globe have publicly shared similar sentiments since mid-December.

Erika Spanger-Siegfried, director of strategic climate analytics in the Union of Concerned Scientists’ Climate and Energy program, warned last week that “in the absence of a clear endorsement of the objective (not the means) of Abramoff and Kalmus’ actions, AGU’s response, coupled with Abramoff’s firing, may be seen by the scientific community as a strong, disapproving, and chilling signal to scientists to step back from climate activism—just when the world needs them to show up in new, courageous ways.”

An open letter addressed directly to the AGU—so far signed by over 2,000 people—says that “we as scientists cannot and must not tolerate this censorship and chilling lack of support from our scientific society and therefore urge AGU to: i) reinstate the scientific contributions of Rose Abramoff and Peter Kalmus to the program; ii) officially rescind any communications AGU may have had regarding this incident with Rose Abramoff and Peter Kalmus’ former or home institutions until after the AGU professional misconduct investigation has concluded; and iii) immediately close the professional misconduct investigation.”

In response to AGU CEO Randy Fiser’s January 11 statement about the demonstration and subsequent investigation, Aaron Thierry tweeted that such protest “is both necessary and justified,” and pointed to an August paper he published in the journal Nature Climate Change with four other climate scientists and a political scientist who focuses on civil disobedience and social movements.

According to Thierry, rather than sanctioning and investigating Abramoff and Kalmus, the AGU “should be backing them in their efforts!”

This post has been updated with HEATED’s additions clarifying that the news outlet independently identified Lauren Parr and Rose Abramoff did not name the AGU official.

Researchers warn Great Salt Lake’s retreat threatens crucial ecosystem, public health

“The lake’s ecosystem is not only on the edge of collapse. It is collapsing,” said one ecologist.

Scientists are warning Utah officials that the Great Salt Lake is shrinking far faster than experts previously believed, and calling for a major reduction in water consumption across the American West in order to prevent the lake from disappearing in the next five years.

Researchers at Brigham Young University (BYU) led more than 30 scientists from 11 universities and advocacy groups in a report released this week showing that the lake is currently at 37% of its former volume, with its rapid retreat driven by the historic drought that’s continuing across the West.

Amid the climate crisis-fueled megadrought, the continued normal consumption of water in Utah and its neighboring states has led the Great Salt Lake to lose 40 billion gallons of water per year since 2020, reducing its surface level to 10 feet below what is considered the minimum safe level.

“Goodbye, Great Salt Lake,” tweeted the Environmental Defense Fund on Friday.

Scientists previously have warned that increased average temperatures in Utah—where it is now about 4°F warmer than it was in the early 1900s—are to blame for a 9% reduction in the amount of water flowing into the lake from streams.

The authors of the BYU study are calling on Utah officials to authorize water releases from the state’s reservoirs and cut water consumption by at least a third and as much as half to allow 2.5 million acre feet of water to reach the lake and prevent the collapse of its ecosystem as well as human exposure to dangerous sediments.

“This is a crisis,” BYU ecologist Ben Abbott, a lead author of the report, told The Washington Post. “The ecosystem is on life support, [and] we need to have this emergency intervention to make sure it doesn’t disappear.”

The shrinking of the Great Salt Lake has already begun creating a new ecosystem that is toxic for the shrimp and flies that make it their habitat, due to the lack of freshwater flowing in. That has endangered millions of birds that stop at the lake as they migrate each year.

The loss of the lake may also already be exposing about 2.5 million people to sediments containing mercury, arsenic, and other toxins.

“Nanoparticles of dust have potential to cause just as much harm if they come from dry lake bed as from a tailpipe or a smokestack,” Brian Moench, president of Utah Physicians for a Healthy Environment, told the Post. Last month, Moench’s group applauded as Republican Gov. Spencer Cox’s administration, under pressure from residents, walked back its position supporting a plan to allow a magnesium company to pump water from the Great Salt Lake.

Abbott called the rapid shrinking of the lake “honestly jaw-dropping.”

“The lake’s ecosystem is not only on the edge of collapse. It is collapsing,” Abbott told CNN. “The lake is mostly lakebed right now.”

Temporarily passing Paris climate targets could ‘significantly’ raise tipping point risk: Study

“To effectively prevent all tipping risks, the global mean temperature increase would need to be limited to no more than 1°C—we are currently already at about 1.2°C,” noted one scientist.

Surpassing the global temperature targets of the Paris climate agreement, even temporarily, could dramatically increase the risk of the world experiencing dangerous “tipping points,” according to research published Friday.

The Intergovernmental Panel on Climate Change (IPCC) defines tipping points as “critical thresholds in a system that, when exceeded, can lead to a significant change in the state of the system, often with an understanding that the change is irreversible.”

Published in the journal Nature Climate Change, the new study focuses on the potential shutdown of the Atlantic Meridional Overturning Circulation (AMOC), the Amazon rainforest shifting to savannah, and the collapse of the Greenland and West Antarctic ice sheets.

Under the 2015 Paris deal, governments agreed to work toward keeping global temperature rise this century below 2°C, ultimately aiming for limiting it to 1.5°C. However, scientists continue to warn the countries’ pledges and actions to cut planet-heating emissions are far from bold enough to reach those goals, and critics blasted the COP27 summit in Egypt last month as “another terrible failure” given that the conference’s final agreement did not call for rapidly phasing out all fossil fuels.

“To effectively prevent all tipping risks, the global mean temperature increase would need to be limited to no more than 1°C—we are currently already at about 1.2°C,” noted study co-author Jonathan Donges, co-lead of the FutureLab on Earth Resilience in the Anthropocene at the Potsdam Institute for Climate Impact Research (PIK). “The latest IPCC report is showing that we’re most likely on a path to temporarily overshoot the 1.5°C temperature threshold.”

The researchers examined various scenarios with peak temperatures from 2°C to 4°C. As lead author and PIK scientist Nico Wunderling explained, they found that “the risk for some tipping events could increase very substantially under certain global warming overshoot scenarios.”

“Even if we would manage to limit global warming to 1.5°C after an overshoot of more than 2°C, this would not be enough as the risk of triggering one or more global tipping points would still be more than 50%,” Wunderling said. “With more warming in the long-term, the risks increase dramatically.”

“We found that the risk for the emergence of at least one tipping event increases with rising peak temperatures—already at a peak temperature of 3°C, more than one-third of all simulations showed a tipping event even when overshoot durations were limited strongly,” he added. “At 4°C peak temperature, this risk extends to more than half of all simulations.”

According to the study, “Our model analysis reveals that temporary overshoots can increase tipping risks by up to 72% compared with non-overshoot scenarios, even when the long-term equilibrium temperature stabilizes within the Paris range.”

Study co-author Ricarda Winkelmann, co-lead of the FutureLab on Earth Resilience in the Anthropocene at PIK, pointed out that “especially the Greenland and the West Antarctic ice sheet are at risk of tipping even for small overshoots, underlining that they are among the most vulnerable tipping elements.”

“While it would take a long time for the ice loss to fully unfold, the temperature levels at which such changes are triggered could already be reached soon,” she said. “Our action in the coming years can thus decide the future trajectory of the ice sheets for centuries or even millennia to come.”

While these scientists found that the Amazon and AMOC have higher critical temperature thresholds, various studies have highlighted the dangers of either system reaching its tipping point.

An analysis of the Amazon released in September by scientists and Indigenous leaders in South America stated that “the tipping point is not a future scenario but rather a stage already present in some areas of the region,” meaning portions of the crucial rainforest may never recover—which could have “profound” consequences on a global scale.

A study on the AMOC from last year, also published in Nature Climate Change, warned that the collapse of the system of currents that carries warm water from the tropics to the North Atlantic “would have severe impacts on the global climate system,” from disrupting rains that billions of people need for food and increasing storms to further threatening the Amazon and ice sheets.

Donges stressed that “even though a temporary temperature overshoot would definitely be better than reaching a peak temperature and remaining there, some of the overshoot impacts may lead to irreversible damages in a high climate risk zone and this is why low-temperature overshoots are key here.”

Pointing to estimates that current policies could lead to an average global temperature of up to 3.6°C by 2100, Donges declared that “this is not enough.”

As Winkelmann put it: “Every tenth of a degree counts. We must do what we can to limit global warming as quickly as possible.”
